drivers/intel/fsp2_0: Make coreboot FSP stack 16-bytes aligned

- Stack alignment:

  1. FSP functions must be called with the stack 16-bytes aligned
     in x86_64 mode.This is already setup properly with the default
     value of the `mpreferred-stack-boundary' compiler option (4).
     Similarly for x86_32 it is set to 2 through compiler option.

  2. The FSP heap buffer supplied by coreboot through the `StackBase'
     UPD must be 16-bytes aligned for x86_64 and 4-bytes aligned for
     x86_32.

BUG=b:329034258
TEST=Verified on Meteor Lake board (Rex)
